How often does the front Torsen Diff need fluid service?

[06z]

I see the question asked a lot about friction mod so i figured I'd clear it up for people who may see this in the future. Friction modifier fluid is needed for differentials that utilize a clutch style limited slip diff. Our E Locker rear diff and Torsen front diff are all gear based differentials, they do not need any friction modifier. This also applies for guys with an open diff.

The point of friction modifier is to help break in clutch style diffs.

Thanks for explaining this. I appreciate it!

So I don't need friction me odifier in my 2019 raptor in the front, correct?

I am thinking about amsoil which it says it includes friction modifier.... So is that enough?

Friction modifier neither helps nor hurts the front Diff, with or without Torsen.
